Welcome to the ULTRACAM (and ULTRASPEC) data archive! At the moment,
we only have the observing logs on-line, but we hope in future to
provide access to raw and reduced data (see below).

Since 09 September 2002, observing logs have been produced using the
ULTRACAM automatic logging system (AutoLogger). Each night,
AutoLogger extracts information automatically from the .dat
and .xml files and combines this with observers' comments read from a
file. Prior to 09 September 2002, the ULTRACAM observing logs were
output as a word document.

The logs below are created immediately after each night of observing.
There exist a second set of logs created by Tom Marsh once each
observing run is over. These logs are easier to navigate than those
below and contain much more information, such as object coordinates,
sample images, and the airmass at the start and end of each run.
Tom's ULTRACAM logs can be viewed
here
and his ULTRASPEC logs can be viewed here
here.

If you require access to a particular dataset, Tom Marsh has now
implemented an automated web-based system which users can access to
download their own data. Please contact Tom for details. Failing
that, ask me and I can put the required data onto an anonymous ftp site.
